Vercel KV Redis Compatibility
Learn about the Redis commands Vercel KV supports.Vercel KV supports commands compatible with the Redis client protocol up to v6.2.
This documentation provides an overview and examples of the Redis commands supported by our Redis database. For a comprehensive understanding of each command and its options, please refer to the official Redis documentation.
The Redis String data type is used to store and manipulate an array of bytes representing a sequence of characters. Here's an example using the SET and GET commands:
> SET user:1 "John Doe"
OK
> GET user:1
"John Doe"Supported commands:
APPENDDECRDECRBYGETGETDELGETEXGETRANGEGETSETINCRINCRBYINCRBYFLOATMGETMSETMSETNXPSETEXSETSETEXSETNXSETRANGESTRLEN
Redis Bitmaps are used to store and manipulate bit arrays. Bitmaps are not a separate data type, but a set of bit-oriented operations defined on the String type. Here's an example using the SETBIT and GETBIT commands:
> SETBIT user:1:flags 0 1
(integer) 0
> GETBIT user:1:flags 0
(integer) 1Supported commands:
Redis Hash is a data type used to store key-value pairs. Here's an example using the HSET and HGET commands:
> HSET user:1 name "John Doe"
(integer) 1
> HGET user:1 name
"John Doe"Supported commands:
HDELHEXISTSHGETHGETALLHINCRBYHINCRBYFLOATHKEYSHLENHMGETHMSETHSCANHSETHSETNXHSTRLENHRANDFIELDHVALS
Redis Lists are ordered collections of strings. Here's an example using the LPUSH and LRANGE commands:
> LPUSH fruits "apple"
(integer) 1
> LPUSH fruits "banana"
(integer) 2
> LRANGE fruits 0 -1
1) "banana"
2) "apple"Supported commands:

Redis Sets are unordered collections of unique strings. Here's an example using the SADD and SMEMBERS commands:
> SADD colors "red"
(integer) 1
> SADD colors "blue"
(integer) 1
> SMEMBERS colors
1) "red"
2) "blue"Supported commands:
SADDSCARDSDIFFSDIFFSTORESINTERSINTERSTORESISMEMBERSMEMBERSSMISMEMBERSMOVESPOPSRANDMEMBERSREMSSCANSUNIONSUNIONSTORE
Redis Sorted Sets are non-repeating collections of strings ordered by a score. Here's an example using the ZADD and ZRANGE commands:
> ZADD scores 10 "player1"
(integer) 1
> ZADD scores 20 "player2"
(integer) 1
> ZRANGE scores 0 -1 WITHSCORES
1) "player1"
2) "10"
3) "player2"
4) "20"Supported commands:

Redis Geo data type is used to store and manipulate geographical information. Here's an example using the GEOADD and GEORADIUS commands:
> GEOADD cities 13.4050 52.5200 "Berlin"
(integer) 1
> GEOADD cities 2.3522 48.8566 "Paris"
(integer) 1
> GEORADIUS cities 13.4050 52.5200 1000 km WITHDIST
1) 1) "Berlin"
2) "0.0000"
2) 1) "Paris"
2) "878.9692"Supported commands:

Redis HyperLogLog is a probabilistic data structure used to estimate the cardinality of a set. Here's an example using the PFADD and PFCOUNT commands:
> PFADD users "Alice"
(integer) 1
> PFADD users "Bob"
(integer) 1
> PFADD users "Alice"
(integer) 0
> PFCOUNT users
(integer) 2Supported commands:
Redis Scripting allows the execution of Lua scripts on the server-side. Here's an example using the EVAL command:
> SET counter 10
OK
> EVAL "return redis.call('INCR', KEYS[1])" 1 counter
(integer) 11Supported commands:
Pub/Sub is not currently supported through the Vercel KV SDK. Instead, you can use the native Redis client.
Redis Pub/Sub allows sending messages between different clients through channels. Here's an example using the PUBLISH command:
> PUBLISH news "Breaking news: Redis documentation updated!"
(integer) 5Supported commands:
Redis Transactions group multiple commands together, ensuring they are executed sequentially and atomically. Here's an example using the MULTI, INCR, and EXEC commands:
> SET balance 100
OK
> MULTI
OK
> INCR balance
QUEUED
> INCR balance
QUEUED
> EXEC
1) (integer) 101
2) (integer) 102Supported commands:
Redis Generic commands provide general functionality for managing keys. Here's an example using the EXISTS and DEL commands:
> SET key1 "value1"
OK
> EXISTS key1
(integer) 1
> DEL key1
(integer) 1
> EXISTS key1
(integer) 0Supported commands:
COPYDELEXISTSEXPIREEXPIREATKEYSPERSISTPEXPIREPEXPIREATPTTLRANDOMKEYRENAMERENAMENXSCANTOUCHTTLTYPEUNLINK
Redis Connection commands are used to manage client connections to the server. Here's an example using the PING command:
> PING
PONGSupported commands:
Redis Server commands provide information and control over the Redis server. Here's an example using the DBSIZE and FLUSHDB commands:
> SET key1 "value1"
OK
> SET key2 "value2"
OK
> DBSIZE
(integer) 2
> FLUSHDB
OK
> DBSIZE
(integer) 0Supported commands:
Redis JSON provides native support for storing and manipulating JSON data. Here's an example using the JSON.SET and JSON.GET commands:
> JSON.SET user . '{"name": "Alice", "age": 30}'
OK
> JSON.GET user
"{"name":"Alice","age":30}"Supported commands:
JSON.ARRAPPENDJSON.ARRINSERTJSON.ARRINDEXJSON.ARRLENJSON.ARRPOPJSON.ARRTRIMJSON.CLEARJSON.DELJSON.FORGETJSON.GETJSON.MGETJSON.NUMINCRBYJSON.NUMMULTBYJSON.OBJKEYSJSON.OBJLENJSON.RESPJSON.SETJSON.STRAPPENDJSON.STRLENJSON.TOGGLEJSON.TYPE
Redis Streams provide a data structure for managing and processing streams of data. Here's an example using the XADD and XRANGE commands:
> XADD mystream * sensor-id 1234 temperature 19.8
"1623791288816-0"
> XADD mystream * sensor-id 5678 temperature 21.3
"1623791288816-1"
> XRANGE mystream - +
1) 1) "1623791288816-0"
2) 1) "sensor-id"
2) "1234"
3) "temperature"
4) "19.8"
2) 1) "1623791288816-1"
2) 1) "sensor-id"
2) "5678"
3) "temperature"
4) "21.3"Supported commands:
Since Vercel KV is a serverless, durable key-value store, you don't need to manage clusters or horizontal scaling.
